Automatic Hotspot Detection

Detect hotspots automatically using Fatigue Analysis.

Figure 1.
Strain-Life uniaxial analysis is supported for automatically identifying critical locations on selected parts. The following options are essential for Strain-Life fatigue evaluation:
Crack Growth Fatigue Module
Set up a Strain-Life fatigue analysis.
See Configure Fatigue Analysis.
Creating and Assigning Strain-Life Material Properties
Create Strain-Life materials and assign them to selected parts.
See Materials.
Creating Fatigue Events
Create time-series–based fatigue events using configuration superposition.
See Load Maps.
Note: Event groups are not supported for fatigue analysis. Only individual event creation is supported. Currently, event groups are supported only for crack growth analysis.
Strain-Life evaluation is launched using the Play button in the Hotspot guide bar with the Creation option set to Automatic.

Threshold Ratio, Damage Limit, and Max. Allowable Hotspots combine to determine the number of hotspot clusters. The node with the maximum damage in each cluster is selected to define the crack growth hotspot in the dialog.
Damage Limit
Nodes with damage values below this threshold are excluded from hotspot creation.
Threshold Ratio
A percentage of the maximum nodal damage, used to define the required clusters.
Number of Hotspots
Specifies how many hotspot clusters should be detected.
Note: The detected hotspot clusters (nodal sets) are created in the crack growth session and are available in the HyperLife Crack Growth Model Browser.
Note: The damage results from the HyperLife Crack Growth session are also available for contour visualization in the Result Browser.
